ENGLISH
The motor’s terminals have no pre-defined
polarity. The postive and negative leads may
be connected to either terminal.
If the pump is to be connected with a
separate grounded cable then the cable is to
be yellow and green in color and connected
to the foot of the pump. The negative lead
should be black.
Choose your cable dimensions according to
cable length as listed in the table.
NB! On installation electrical components
and eventual control systems must be
dimensioned for the motor’s power
consumption. Underdimensioned
components can cause excessive heating and
fires.
Switches, relays and fuses must be of
ignition-protected type.

Electrical installation must be according to
ISO 10133.
Other electrical devices, eg switch, circuit
breaker, must be installed between the
pump and the positive (+) lead on the
battery (on the red wire).

The wire length is the total distance from the battery
to the pump and back to the battery. Use cord
standing moist environment.
When the pump is used as a bilge pump
Max total head 7 m.
The pump must be installed so that the
motor is protected from splash from bilge
water.
The pump must be fitted with a strainer or
filter preventing debris from entering the
pump.
Self-priming
Pump is self-priming up to 4 m. Intake lines
must be air-tight to ensure self-priming.
Note: Pump will prime when impeller is dry
but suction lift up to 4 m is only obtainable
when impeller is greased or lubricated with
liquid being pumped. For permanent
installations where suction lift exceeds 4 m,
a foot valve should be used to assure
priming on start up. All performance figures
stated are for water at 20
°
C and at full
voltage of the motor.
Note: Max continuous operation for motor 1
hour at 1 bar pressure.
Dry running
Do not run dry for more than 30 seconds.
Lack of liquid will burn the impeller and
damage the seals.
Caution
Do not pump gasoline, solvents, thinners,
highly concentrated or organic acids. If
corrosive fluids must be handled, pump life
will be prolonged if flushed with water after
each use or after each work day.
Motor is
not explosion proof.
